Visualize the relative number of hydroxide ions and hydronium ions in solution. PhET: pH Scale Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.PhET: Molecule Shapes: Basics Explore molecule shapes by building molecules in 3D! Find out how a molecule's shape changes as you add atoms to a molecule.Then, compare the model to real molecules! PhET: Molecule Shapes Explore molecule shapes by building molecules in 3D! How does molecule shape change with different numbers of bonds and electron pairs? Find out by adding single, double or triple bonds and lone pairs to the central atom.Use the sim to explore how light interacts with molecules in our atmosphere. PhET: Molecules and Light Do you ever wonder how a greenhouse gas affects the climate, or why the ozone layer is important.Change solutes to compare different chemical compounds in water. PhET: Molarity What determines the concentration of a solution? Learn about the relationships between moles, liters, and molarity by adjusting the amount of solute and solution volume.PhET: Isotopes and Atomic Mass Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other. PhET: Gas Properties Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, change gravity, and more.Can a weak acid solution have the same pH as a strong acid solution? Then see how concentration and strength affect pH. PhET: Density How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals and find out how concentrated you can go before you hit saturation! Then check molarity with the concentration meter. PhET: Concentration Watch your solution change color as you mix chemicals with water.PhET: Build an Atom Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change.View the color of the peak of the spectral curve. Adjust the temperature to see the wavelength and intensity of the spectrum change. PhET: Blackbody Spectrum How does the blackbody spectrum of the sun compare to visible light? Learn about the blackbody spectrum of the sun, a light bulb, an oven, and the earth.PhET: Beer's Law Lab “The thicker the glass, the darker the brew, the less the light that passes through.” Make colorful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer!.PhET: Balancing Chemical Equations How do you know if a chemical equation is balanced? What can you change to balance an equation? Play a game to test your ideas!.Customize the attraction to see how changing the atomic diameter and interaction strength affects the interaction. Observe the the total force acting on the atoms or the individual attractive and repulsive forces. PhET: Atomic Interactions Explore the interactions between various combinations of two atoms.PhET: Acid-Base Solutions How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity.
